isn't that (Catholicism) another denomination of Christianity?
also...
why is it always Catholic and everything else...instead of another denomination of Christianity?
These are great questions. I think what is at the heart of these questions is a true desire to know and understand why the line is drawn between Catholicism and Protestantism. Sure, there are lines drawn between various Protestant denominations, but there is a true and undeniable distinction between Catholics and Protestants. This distinction sometimes leads people to believe that one or the other, or perhaps even both, are not Christian at all.
The point of this discussion is to talk about why is there such a distinction. Why is it always Catholics and everyone else? To kick things off, I would like to start by offering a possible explanation...
The term Protestant literally means, someone who protests. Well, what is a Protestant protesting against? Protestants are actually people who protest against the Catholic Church. In one way or another, they do not accept the teachings of the Catholic Church. As a matter of fact, most Protestants denominations, identify themselves as to how much or how little their belief system aligns with the belief system of the Catholic Church. The Catholic Church is the standard that many denominations measure against. For that reason, the comparison is always Catholics and Protestants, as oppose to Baptists and Catholics, when talking about Christianity.
Thoughts?
